A pyrrolesulfonamide compound having the following formula (I):
1
wherein the ring P represented by
2
is a pyrrole ring having the following structure:
3
wherein A represents alkylene, alkenylene or alkynylene; and Y represents a group
4
which W represents CH, C═ or N; m stands for 0 or 1 when W is CH or N, or m stands for 1 when W is C═; B represents a specific divalent group; E
1
and E
2
each independently represents H or lower alkyl; and D represents an aromatic hydrocarbon group or heterocyclic group; l stands for 0 or 1; the dashed line indicates the presence or absence of a bond; and, when the bond is present, Z
2
is not present and Z
1
represents H but, when the bond is absent, Z
1
represents H and Z
2
represents OH or Z
1
and Z
2
are combined together to represent O or a group NOR
5
, in which R
